Class PreJoinableClause

java.lang.Object

org.apache.druid.query.planning.PreJoinableClause

public class PreJoinableClause
extends Object

Like JoinableClause, but contains a DataSource instead of a Joinable. This is useful because when analyzing joins, we don't want to actually create Joinables, since that can be an expensive operation.
